Description
Benefits
L-theanine works as a nootropic by providing an increase in alertness and attention while still acting as a relaxing aging. Studies show that prolonged use of L-theanine can also be beneficial for memory, but the primary effects are utilized for short-term neurotransmitter alteration including increased GABA and serotonin. Even students with ADHD using L-theanine improve their ability to focus.
Ample evidence proves L-theanine works synergistically with caffeine to negate the side effects while amplifying the benefits. Anxiety and jitters caused by caffeine are reduced by L-theanine supplementation. We provide an extra strength capsule that provides 200mg of 99% pure L-theanine per capsule. The benefits of sublingual solution is better and faster absorption that largely bypasses the first pass metabolism.
Dosage
The recommended dosage for L-theanine is as little as 100mg, though sublingual solution will be more effective. The capsules are considered extra-strength in the the dosage is 200mg/capsule. However, the effects of L-theanine are felt in dosages as low as 50mg and young adults take between 50 – 400mg per day. The safety and low chance of toxicity allows for higher doses in some individuals. The average green tea drinker gets around 20mg of L-theanine per day.
Taking L-theanine with caffeine is effective with a 1 caffeine to 2 L-theanine ratio. With a regular 8 ounce cup of coffee, there are 100mg of caffeine suggesting 200mg L-theanine should be supplemented.
Mode of Action
L-theanine crosses the blood-brain barrier and increases levels of dopamine and serotonin the brain. It is also responsible for modulating AMPA, Kainate, and, NMDA receptors. The mode of action includes increasing GABA activity in the brain as well.
Toxicity
L-theanine has a high threshold for toxicity. Animal studies have shown no irreversible side-effects in rats with doses of 500mg / kg of weight. For a 150 pound individual, this equates to 34,000mg of L-theanine. However, headaches are a side effect of overdose in some individuals.

Full Analysis
L-Theanine is an amino acid found primarily in tea. It has been used as a relaxing agent in traditional Chinese and southeast Asian societies for thousands of years and only recently was discovered in molecule form. In 1949 scientists isolated the compound and it was approved for use in foods as early as 1964.
L-Theanine Benefits
There are a variety of benefits to using L-theanine. Namely, users find that it is a great way to increase relaxation and feelings of calmness. This is a result of the alpha brain wave improvements that come with this amino acid. This calmness has a few different effects. For one, L-theanine is a natural anxiety treatment that helps people to sleep better. By removing anxiety, many people are able to get a better night of rest or at least enhanced sleep quality.
The other health benefits of L-theanine are applicable to most people as well. Combining L-theanine with caffeine is supposed to be a great natural ADHD treatment for many people. Studies show that combining the L-theanine and caffeine with a 2:1 ratio is perfect for general focus and attention. This is obviously a lot healthier of an option than Adderall and amphetamine-based drugs. Using L-theanine for children is a really valuable tool in the long run.
The L-theanine studies that currently exist show that the drug is one of the safest that you can find. The FDA has labeled it “GRAS” or “generally regarded as safe”, which symbolizes their unique view on this nootropic compound.
Buy L-Theanine
Even though L-theanine is fairly easy to find, getting the best L-theanine supplement is not always a simple task. There are many caveats and biological differences with regard to L-theanine that make it have differing effects. For example, if you buy L-theanine sublingual solution then you will find it is better absorbed and has a stronger impact on your body.
You may find products online or in your local health food store, but L-theanine is best purchased with a vendor that you know and trust. As Pure Nootropics has shown, there are third party certificates on many of the products with heavy metals and assay testing. Beyond the reputability factor with our brand, there are the unique and novel opportunities with the sublingual solutions. These are more effective than taking the powder or capsules orally and can make a bigger difference for your brain health.

I’ve been taking l-theanine for several month to aide with my anxiety. I really like the sublingual solution you guys provide mainly because it is convenient to carry with me. I’ve been using the l-theanine as an additive to my coffee and it has been working well.
